I've read that even though Santorum won and Romney was a close second, Ron Paul walked away with 21 of the 30 delegates because the Iowa caucus doesn't have squat to do with how the delegates are selected in Iowa.
Yeah, it’s screwy. Paul got 22, Romney got the other 6. The “winner” got none.
I’m not even sure why they vote for candidates, as, as far as I understand it, what really matters is who they elect as delegates to go to the county convention to elect delegates to the state convention, who will ultimately vote on how to proportion the State’s delegates in the primary.
